Digital Domain Media Group, the Florida-based digital effects company behind the Tupac Shakur hologram that wowed 'em at Coachella, has been in a downward spiral since spring. After staging an IPO last year, the company peaked at around $9 a share. It's now fallen below $1. The CEO, John Textor, resigned today.

DDMG has been an integral part of the visual effects of "Transformers" and "Tron," as well as "Thor." The company's market capitalization has plunged to about $24 million, making it worth less than its apparent total debt of $35 (debt that was just extended by bondholders).

The company is miles from where it was in late May, when executives rang the bell at the New York Stock Exchange.
